Analog Circuit Design for Consumer Electronics

Job ID: 39964642

Budget: £20 – £250 GBP

I want a breadboard circuit that can be used to detect a voltage (any voltage from 9v - 53v on a device that delivers 53v for 0.1 seconds through 2 wires).

I want there to be 4 sets of crocodile clips to measure the 4 circuits, a green LED to indicate the power is on, and 4 red LEDs that indicate what circuit has voltage on it and the LED is to stay on when power is detected.

I also want a buzzer that will sound for 1 second when voltage is detected.

I want a switch for power and a button that can be used to reset the LEDs to off.

I want it to run off 4 AA batteries
